Common control channel (CCC) is necessary for some MAC protocols. However, in cognitive radio networks, CCC is hard to establish. Proposed MAC protocol solves multichannel hidden terminal, broadcast message, and load balance problems. In addition, proposed MAC protocol also solves the problem of common control channel, and cooperative sensing. In addition to above mentioned problems, it’s more important that MAC protocols should provide good throughput and delay time. Proposed MAC protocol uses channel hopping technique and split-phase to solve those problems and it maintain a good performance of throughput and delay time.5415399 bytesapplication/pdfen-US感知無線電網路通訊協定跳頻多通道隱藏終端問題共同控制信號通道時間同步多節點Cognitive Radio NetworksProtocolMultichannel hidden terminalCommon Control Channel HoppingSynchronizationMulti-Hopthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/252893/1/ntu-100-R98942127-1.pdf
